3.3 Air supply
3.3.1 Air quality
1) Using compressed air which contains chemicals, synthetic oils containing organic solvents,
salts or corrosive gases, etc. can cause damage or malfunction. Do not use with fluid or in an
environment which contains harmful impurities.
2) If the compressed air contains excessive drainage or carbon powder, it can stick to the vacuum
generating part (the nozzle diffuser) or inside of the solenoid valve or the pressure switch for
vacuum and cause deterioration of the performance or operation failure.
3) It is recommended to use supply air which purity class is 2:6:3 of ISO08573-1:2010
（
JISB8392-
1:2012
）
. Supply air containing foreign matter, water, oil or condensate, etc. can cause malfunction
of supply valve or release valve. Install an air filter or mist separator to the upper stream to prevent
condensate from entering to the product and perform maintenance periodically to control the
supply air properly.
